LEO CAREER, OF DUSSELDORF, GERMANY.

PAPER-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 445,923, dated February3, 1891.

Application filed July 25, 1889. Serial No. 318,674. (No model.)

To all whom it may concern.-

Be it known that I, LEO GARRER, a subject of the Emperor of Germany,residing at Dusseldorf, in Rhenish Prussia, in the German Empire, haveinvented a new and useful Improvement in Paper-Cutting Machines, ofwhich the following is a specification.

The object of the invention is to produce a machine which will cut paperin an easier and smoother waythan machines now in use by giving theknife a horizontal reciprocating motion as it cuts downward through thepaper.

The nature of the invention consists in the details of combination andconstruction, substantially as illustrated in the accompanying drawings,hereinafter described, and subsequently pointed out in the claim.

Figure 1 is a front view of a paper-cutter constructed according to myinvention. Fig. 2 is a sectional view illustrating the wheel Fig. 3 is aplan view of the same. Fig. 4. is a transverse sectional viewillustrating the working parts of the machine. Figs. 5 and 6 arediagrams to illustrate the motion of the knife.

The frame of the machine is designated at A A. Upon a shaft journaled inthis frame is mounted the pinion 0'. Upon this same shaft is mounted thewinch 00. Upon another shaft journaled in this frame is mounted thespur-wheel r, which is engaged by the said pinion 0'. Upon this sameshaft is formed the crank S and mounted the pinion 4' Upon a thirdshaft, also journaled in said frame, is mounted the spur-wheel r whichis engaged by the pinion T The connecting-rod S connects the said crankS and the knife-beam S. This knife-beam is free to slide between theguides A A.

Upon the wheel 1' is a crank-pin H", to which is attached theconnectingrod 1-1.

.This rod connects the said pin and the lever 11*. The lever I1 ispivoted to the frame of the machine at 72,. A slide (designated by B) isalso arranged to slide in said frame. It is connected with the lever 11by the rollers R R. This slide is also pivotally connected with theknife-beam S by the rods B These rods consist of two pieces B and B Oneof these has upon its end a right-hand screw, the other has a left-handscrew. Upon these two screws is the nut B, by means of which the lengthof said rodmay be adjusted. A table K and a clamp P are provided to holdthe paper to be cut in the machine. A radial slot h is cut in the Wheel1- and the length of the movement of the lever H may be regulated bychanging the pin H to different distances from the center of said wheelin said slot. If, however, but one length of motion be desired for thelever 11 an eccentric groove (designated by H" of Fig. 3) may be usedinstead of the pin H and with a proper connection on the rod H.

To use this machine, the operator first clamps the paper to be outbetween the clamp P and the table K, as illustrated in dotted lines inthe drawings. Then taking hold of the winch W he begins to turn it. Ashe turns, the wheels 4" r r r begin to revolve and the crank S to turn.As it turns on account of being connected to the knife-beam by the rodS, it produces a horizontal reciprocating motion of the said knife-beamand the knife it carries. At the same time the wheel r turning moreslowly by means of the crank-pin H and lever 1-1, pushes down the leverH This draws down the slide 13, which, being attached, as aforesaid, tothe knife-beam S, draws it down too, gradually carrying the knifethrough the paper as it on ts. The knife is then forced to take a zigzagcourse through the paper, the course, if the pin 71. be employed, beingrepresented by the diagram, Fig. 6, the angle of the zigzags will begreatest at the middle of the stroke of the knife through the paper andleast at each end; but if the eccentric groove or cam be employed, theangles of the zigzag course of the knife will be all equal, asrepresented in Fig. 5, as long as the eccentric part of the grooveactuates the lever h while the course represented by Fig. (3 will betaken by the knife on its upward stroke-2I. 0., when the lever isactuated by the concentric half of the groove or cam.

It is evident that any well-known connection may be used to supplyactuating-power instead of the winch IV.

hat I claim as my invention, and desire to secure by Letters Patent,is-

The combination, in a paper-cutter, with the supportingframe of themachine, a train of wheels journaled in said frame, a crank said lever,adjustable rods pivotally connectconnected with and revolved by saidwheels, a clamp and table for holdingpaper while hea knife, a beamcarrying such knife and sliding cut, and means, substantially asspecified, ing in said frame, a connecting-rod connectfor actuating saidmachine, all substantially ing said knife-beam and said crank, of a K asand for the purpose set forth.
